The type of roofing tile on building materials market has a lot of in present roof, but what be worth comparing at present is glazed tile, colour steel tile, synthetic resin tile these 3 kinds, which kind is good in the end? Which one is durable? Let's take a look.

The main components of glazed tiles are silicon dioxide, alumina and lead oxide, which appeared initially as a by-product of bronze ware. Glazed tiles are ceramic products with translucent glaze on the surface. Glazed tiles are made by firing at a high temperature and are covered with a layer of glaze which adds a lot of color to the tile itself. The problem also appeared from this, in the cold in winter will contract, summer high temperature will expand, heat expansion and cold shrinkage this phenomenon makes the glazed tile is easier to crack, in addition, when the surface of this glaze cracks, it will seepage water, repair nature became a big problem. Because the glazed tile is a piece of put together, there is a crack, you have to open the whole piece, this is a very big disadvantage of the glazed tile.

Color steel tile is a sheet of double-sided spraying, processing into a variety of corrugated to give the sheet good mechanical, as roofing tiles. Color steel tile color generally maintain 5-10 years, service life in 10 to 15 years between the color steel tile is generally used in the workplace such as the heat insulation and sound insulation effect requirements are not high. And be used at living and office wait for the place with taller requirement to sound insulation effect is inappropriate, in addition his price is different according to his board thickness, the coating treatment of the surface, the price also can have bigger discrepancy.

Synthetic resin tile is a domestic advanced three-layer co-extrusion technology, synthetic resin tile is mainly composed of ASA ternary polymer (ASA) and polyvinyl chloride (PVC), auxiliary materials to curing agent, accelerator, diluent, flame retardant, uv absorbent, fillers, pigments, release agents and other materials made of polymer. It is similar in some properties to natural resins. The raw material of synthetic resin tile is resin extracted from petroleum. Low temperature resistance, high temperature resistance, anti-fading, the service life of the National Chemical Materials testing Center has the status of qualification recognition. Compared with the traditional tile, ASA synthetic resin tile has the advantages of acid and alkali resistance, corrosion resistance, heat insulation and easy installation, etc. It is also designated ASA special material for China's slope renovation project.
